Lightbulb Guitar Amp

Good Day!

I have attached a pdf of a guitar amplifier I built - I call it the Bug Eyed Monster because The speaker grills on the case make it look buggy eyed. I use this amplifier primarily with either an external audio or with my piezo pickup equipped nylon string guitar.

Based upon the TDA 2003 chip. pics to follow

Itīs a beauty amp ! Congratulations !
Two questions :

1) Is the buffer output used to connect to a bigger amp ?
2) Are the RCA inputs used to connect a MP3 player (or something like that) and play the guitar at some time ?

Thank You!

1) Indeed, the buffered output is for connection to another amplifier or a house system.

2) The RCA inputs are used when I play a CD/TAPE/MP3 or Radio headphone output through the amplifer. I haven't tried running the guitar through as well. However, the FET front end that the Guitar sees buffers that input from the RCA jack - would probably work, IMHO>
